A collection of battery-powered devices designed to be worn by a person (typically a child) wearing a compatible hearing aid to enhance the sound quality they receive by reducing background noise and/or room reverberation potentially found in a teaching environment (e.g., a school classroom). It uses a set frequency modulation (FM) between a transmitter worn by the speaker (e.g., a microphone worn be the teacher) and the FM receiver worn by the user. It typically consists of the FM receiver, a neck induction loop that emits the sound locally to the hearing aid, a battery charger, and various cables enabling connection to digital music devices.
